= 33,000 EUR (net) (of which 5,000 EUR for heating installation)

2 bathrooms (2x walk-in showers, 1 bathtub, 2 washbasins, 2 rimless toilets, 1 urinal, towel radiator) — all standard; without bathroom furniture; complete with installation
= 13,000 EUR (net) (of which 4,500 EUR for sanitary installation)

Thanks!

hey bathrooms without tiles?

Only for standard sanitary fixtures €13,000? Or does that include the entire domestic water installation as well? Far too little information...
We paid just a fraction of that for 2 bathrooms of the same size (no urinals) with high-end ceramics/showers...

Addition to the description.

Sanitary:
- The sanitary installation and domestic hot water (DHW) system are included in the 13,000 EUR; however, the connection for potable water and wastewater from the property to the street is an additional cost.
- The price does not include tiling work.
